Power supply device for vehicle charging

Abstract

Provided is a power supply device for vehicle charging, which comprises a power receiving side device (9) connected with electric equipment, and a power supply side device (8) electrically connected with a power source. The power receiving side device (9) can realize power supply by moving close to the power supply side device (8) with the electric equipment. The power receiving side device (9) comprises a base frame (91) and guide rods (92) supported by a support arm (93) fixedly connected with the base frame (91). The guide rods (92) are slidably provided with a power supply plug device (94) capable of being electrically connected with the electric equipment through an extendable cable (940).

Description

technical field [0001] The invention relates to the field of power supply, in particular to a power supply device for charging a vehicle. Background technique [0002] In occasions where power supply is required, it is often necessary to supply power to, for example, some motorized equipment, such as charging transport vehicles for indoor use and electric vehicles for transportation. In order to realize the electrical connection between the vehicle and the power source, it is often necessary to manually electrically connect the connector of the vehicle or the electric device to the power charging device. This often brings inconvenience to the operation and reduces the work efficiency in occasions where work efficiency is required to be high and where manual operation is inconvenient. Moreover, it is difficult to disconnect the charging in time, especially in the case where a mechanical connection is required to ensure charging reliability and safety, it is difficult to disc...

AI Technical Summary

Problems solved by technology

This often brings inconvenience to the operation and reduces work efficiency in occasions where work efficiency is high and where manual operation is inconvenient.

And it is difficult to achieve timely charging disconnection, especially in the occasions where mechanical connection is required to ensure charging reliability and safety, it is difficult to disconnect both electrical and mechanical connections

And some ways of directly mechanically connecting the plug of the electrical equipment to the power supply through the motorized movement of the electrical equipment can solve the problem of fast electrical connection, but it has a high accuracy for the mechanical movement positioning of the electrical equipment. Requirements, it is difficult to meet the position error fault tolerance problem caused by inaccurate stop position of electrical equipment
